i m a female 66 yrs. old, in good shape, but for the last 5 days, after i eat, on my left side under my breast, i have like a pain, that comes and goes, it s scary for me as i ve never had this before. I like to move a lot, walk guarding & exercise. I can shovel snow for 2-3 hrs. not stop & don t feel tired, i never had what i have now, but only after i eat. Please reply and thank you so very much. My name is Teresa
